Sub woofer questions?

i have a set of sound storms there peak power is 2000 watts each and the rms wattage is 1000 and right now i have 250 rms going into each and they shake the hell out of my car so if i get the proper amp it will be insane like i have to have everything turned right down and it still shake and the subs make my amp kick out because the subs are draining to much power and these subs you can get online for 60 some odd dollars each
